Biorefined perennial ryegrass press cake as an alternative feed for dairy cows in late lactation and during the dry period: a demonstration

HIGHLIGHTS

• What: The aim of this study was therefore to investigate the potential application of partially replacing PRG silage with PRG press cake on productivity and enteric CH4 emissions of late lactation and non-lactating spring calving dairy cows. In the present study, cows offered GSPC in late lactation produced more milk, milk solids and FPCM compared to those offered GS, with the gap between the aforementioned milk production parameters of GS and GSPC cows widening week-on-week until the cows were dried off.
• Who: H. Costigan and collaborators from the University College Dublin, Belfield . . .
